A STOLport or STOLPORT was an airport designed with STOL operations in mind, usually for an aircraft class of a certain weight and size. The term "STOLport" did not appear to be in common usage as of 2008, although was commonly used by pilots flying into Biggin Hill during 1986/87 when the London City Airport was opened restricting approaches and ceilings to the north of Biggin. A STOLport usually has a short single runway, generally shorter than 1,500 m (5,000 ft). STOLports are only practicable by certain types of aircraft, especially smaller propeller aircraft, with performances that are compatible with the shorter runway length, steeper approach/departure paths, etc. at individual STOLports. In the United States, short runway facilities are simply known as airports, and the term "STOLport" has not been commonly used since the early 1970s.
